Environment setup for C++ program

Before you create a C++ program, you must install C++ Compiler. The compiler is
a software that enables a program to be created to communicate with the computer
systems. There are many compilers that can be used in C++ programming, which
include Dev C++, Boland C++, and Visual C++. Other compilers are available
online. All examples in this book were prepared using Dev C++.

Installation of Dev C++ compiler
The following are steps to install Dev C++ compiler (Based on Version 5.11):
Step 1: Using any search engine, download a complete version of Dev C++
depending on your operating system by clicking the button “Download”
as shown in Figure 4.10.
